Replacement of Battery
When replacing the battery, note the following
precautions and be sure to stop the engine
and remove the key before replacement.
Danger
Danger
Do not replace the battery near open flames
or in a poorly ventilated area. Keep the battery
away from lit cigarettes and other open
flames.
Failure to observe these precautions could
cause a fire or explosion.
Do not short-circuit the battery.
If the positive and negative terminals are
connected to each other by a metallic tool, the
battery will short-circuit. And a short-circuit will
also occur if the positive terminal contacts
another metallic part (machine body, etc.).
When connecting a machine-side cable
terminal to a battery terminal, ensure that the
nut is firmly tightened.
A loose nut could cause a fire or explosion.
Warning
When connecting the machine-side cable
terminals to the battery, ensure that they are
correctly connected to the positive and
negative terminals.
Secure the battery firmly with the mounting
bracket.
Failure to do so could cause damage to the
battery, leakage of the electrolyte, fire or
explosion.
Do not modify the battery terminals.
Ensure that the vent plug or vent hole on the
side of the battery is not covered by the
connection cables, etc.
Do not connect any electrical devices directly
to the battery.
Caution
Select a battery that has the same terminal
positions (the positions of the positive and
negative terminals) as the old one.
Installing a battery that has different terminal
positions could cause damage to the cables.
Do not use organic solvents such as benzene,
thinner or gasoline and refrain from using
cleaners.
Do not allow the battery to come in contact
with vinyl chloride containing plasticizer, etc.
When handling the battery, keep it in a
horizontal position and install it on the
mounting so that it is horizontal.
If the battery has terminal covers or heat
shield plates attached, re-install them in their
original positions after replacing the battery.
When mounting the battery on the machine,
never hold the battery terminals.
Doing so could cause the terminals to deform,
resulting in poor connections or electrolyte
leaks from around the terminals.
Replace the battery with one that has the
same size.
